The pneumatic bones are where the air sacs, part of the respiratory system, connect with some of the longer bones. These bones are hollow to help with flight.

Invertebrate animals are animals that have NO bones, such as crabs. Vertebrate animals are animals that HAVE bones, such as dogs.

Not really. It does have a hydro-skeleton where it uses pneumatic pressure to move along.
All animals have bones.
It depends on which animal you are talking about. Some animals without bones are larger than animals with bones. Compare the Giant Pacific Octopus with a mouse.
